As NASA¹s Cassini spacecraft approached Saturn last July, it found evidence that lightning on Saturn is roughly one million times stronger than lightning on Earth.

That's just one of several Cassini findings that University of Iowa Space Physicist Don Gurnett will present in a paper published Thursday, Dec. 16 in Science Express, an online version of the journal Science, and in a talk to be delivered at the December meeting of the American Geophysical Union in San Francisco.
